No. The MIPS machine will run open-source Linux. Let me state my purpose more clearly: Before adding Ruby to the pre-existing Make system for the MIPS-based platform that I have, I'm trying to cross-compile and build Ruby on the Debian m/c in order to get an approximation of the memory footprint.

I have done that already. And "irb" does work on my x86 workstation running Debian.
